First of all, we should analyze the presence of mechanical obstruction factors from the medical history. Dynamic intestinal obstruction includes common paralytic and rare spastic intestinal obstruction; mechanical intestinal obstruction is characterized by paroxysmal intestinal colic hyperacusis and asymmetric abdominal distension; while paralytic intestinal obstruction is characterized by absence of colic and disappearance of intestinal sounds and uniform distension of the whole abdomen; spastic intestinal obstruction can have sudden onset of severe abdominal pain and disappearance of intermittent irregular bowel sounds that are diminished and X-ray abdominal plain films can help to distinguish them: intestinal distention in mechanical obstruction is limited to the intestinal segment above the obstruction site; in paralytic obstruction, all the stomach, small intestine and colon are distended to approximately the same extent; in spastic obstruction, the intestine is not obviously distended and dilated. X-ray abdominal fluoroscopy or radiography is helpful to confirm the clinical diagnosis and determine the site of intestinal obstruction. In a normal person, only a small amount of gas can be seen in the stomach and colon on an abdominal radiograph. If there are gas and fluid planes in the small intestine, it indicates that the passage of intestinal contents is obstructed, suggesting the presence of intestinal obstruction. Acute small bowel obstruction usually takes hours for sufficient fluid and gas to accumulate in the intestine. The degree of intestinal dilatation after hours of significant fluid plane formation certainly reaches a diagnostic level, and colonic obstruction progresses to the point where radiographic signs appear much longer Inflated small bowel, especially jejunum, can be identified by the circumferential folds across the intestinal canal and can be distinguished from a colon with colonic pouching. In addition, the typical small intestine intestinal pattern is mostly in the central part of the abdomen, while the colon shadow is around the abdomen or in the pelvis, according to the patient’s physical condition can be taken from the frontal or lateral position in a standing or horizontal position, and if necessary, a series of films. Suitable food: 1, it is appropriate to eat light and nutritious, liquid food, such as rice soup, vegetable soup, lotus root powder, egg flower soup, noodle flakes, etc. 2.In addition to liquid food also includes rice porridge, vegetarian noodle raw, vegetarian hanging noodles, vegetarian wontons, bread, cookies (less oil) and a small amount of crushed soft vegetables, fruits, etc. 3.It is appropriate to increase the porridge, steamed egg white, a small amount of southern tofu soup food. 4, the use of vegetable fats, more boiled, steamed, cold, roasted, baked, brined, stewed and other ways to cook.
